This invention relates to electric heaters and has for an objeet aheater for circulatingheated air. around the engine of an automobile forthe purpose of facilitating starting the engine, 3 "according tooneembodiment of thisinvention, the heater 'coniprisesahot air flue and oneor n ore cold air flues so arranged that the outlet of the "hot airflue-"andthe inlet of the told with the face of the radiator iof anautomobile at adjacent points. By virtue of this' arrang'ei'nent, heatedair is projected through the radiator into the space below 4' part atleast is drawn back through the radiator into thejcold heating. Duringoperation of {the device partially heated air is drawn into the Gold ailof "fresh air, thereby inof the heater. If a the radiator and hood "flueor fines instead creasing the efficiency blanket be thrown over to coverthe louyres at the side the hood,

the efiectof the heater is increased.

The chambersformed by the members 27 and 28 and the plate 29 are in alignment withthe lines 19, and 21 and form horizontal extensions thereof. A slot 31is provided in the plate 80 and on the plate 29 is provided a stud 32arranged within the slot 31 to limit the sliding movement of the plate29.

In the fine 21 at its upper end is provided a deflector 33, the ends ofwhich are riveted to the partitions 17 and 18 and which acts as a braceas well as a deflector. Straps or other like flexible members 3% and 3501 a W1C th approximately equal to the Width 01 the members 27 and 28are attached to the frame 26 and extend over the upper edge oi the frontwall and down along the inner sur face thereof, the free ends beingattached to the endsoit springs 36 and 3?, the opposite ends of whichare rigidly attached to the body. lVhcn the member 26 is pulled out,these straps substantially close the bottoms of the projecting portionsof the members 27 and. Adjustable legs 38 and 39 are provided tor thebody by means of which its height may be varied. Each of the legs 38 and39 is slidably arranged between the body 10 and a metal strap 40 rivetedto the body at 41. Bolts 4L2 carried by the body 10 exin the legs andapertures in the straps 4L0; wing nuts 4% are threaded on said bolts forclamping the straps it) against the legs to hold them in adjustedposition.

Vi hen this heater is in use,'it is placed in front of the radiator asshown in Fig. 1, with the legs 38 and 39 properly adjusted and themember 26 pulled out so that its end is in contact with the radiator.Air in the flue 21 is heated by the heating element- 25 and caused torise through the line from whence it is. discharged on to the face ofthe radiator through the middle horizontal chamber. The heated air isprojected through. the rav dialor and circulated around the engine blockunder the hood and is returned in part at least through the radiator tothe inlets of the lines 19 and 20 through which it passes and isconducted up around the platform 2.4 into contact with the heatingolenicnt 25. Because of the arriuigcinent oi the lines 19 and 20, andbecause ot the straps 33 and 35, any substantial intlux oi fresh coolair to the heater is prevented. Substantially all the air returned tothe heater is air which has previously been heated and circulated aroundthe engine. The return of partiallyheated air for further heating givesto this device a very high efficiency and definitely assures that theengine will be kept at such temperature as to prevent congealing ot theAlso the circulaion of heated air through the radiator will tend toprevent freezing of the circulating fluid. A blanket thrown over theradiator and hood will prevent the escape of heated air through theradiator and the louvres of the hood, thereby mate-.
